A Brief History

Challis began in 1876 when Alvah Challis platted the town as a supply depot for the growing number of mines and ranches in the area. You can still see many of the original buildings in Challis's downtown on Main Street.

In 1881 Custer County was formed, and Wells Fargo opened a branch office in Challis. By 1896 the area was embroiled in the sheep and cattle wars as Challis was home to a large sheepherding population. Sheepherding had replaced mining as the foremost industry. In 1918 the sheep population of the state of Idaho was 2.6 million - meaning we had six times as many sheep as humans! Annual sheep celebrations are still held over the hill in Hailey, Idaho.

Earthquake!

On October 18, 1983 Custer County was rocked by an earthquake. The quake caused miles of surface faulting along the western flank of the Lost River Mountain Range. The fault line of the massive earthquake of 1983 is located 35 miles southeast of Challis and the scarp is still visible at Mt. Borah, east of Highway 93.
